The "Eeveelutions are special types" argument is not just outdated, but merely a coincidence...in a sense.
You see, there was two similar things going on there:
1st gamefreak had to decide which types would be physical and which special, and the reasoning was that all those that are more material and less energetic phenomenom, were made physical. You know, Fight, Rock, Ground...
And those that felt very elemental were made special. When you think of elements, you think of Fire, Water, Electric...
the 2nd thing is, the concept behind Eevee is that it is an average pet-like mammal which gains elemental powers upon exposure.
These 2 things simply share the same reasoning and ended up with lots of the same choices (the types that are elemental enough were made special, and eevee was made to evolve into the types that are elemental).
Dragon was probably one of those types that was decided to be special so there is a more even number lol.
Also, Dark was made special back in gen II because Steel was clearly the more appropriate candidate for physical...so Umbreon wouldnt be justified now that 95% of Dark moves are physical LOL.
